On the sixth anniversary of their first date, Ashton Eaton and Brianne Thiesen-Eaton skipped the fancy dinner and were in bed by 9 p.m., forgoing romance for much-needed rest. A big afternoon awaited.

This is the cost of living as an elite athlete: Training and competing trump all. On Saturday, the Eatons — both world-class, multisport athletes — were rarely more than a long jump away from each other at the 107th Millrose Games at the Armory in Manhattan, where they competed in two events each.

Ashton Eaton, the 2012 Olympic and world decathlon champion, finished fourth in the 60-meter hurdles (he has said he plans to add the 400-meter hurdles to his event list) and set a personal mark in the pole vault (5.35 meters).

Brianne Thiesen-Eaton, a Canadian heptathlete, finished fifth in the women’s 60-meter hurdles (8.17 seconds) and fourth in the long jump (6.18 meters).

They began dating as classmates at the University of Oregon — their first date, on Valentine’s Day in 2008, took place at an Olive Garden near campus — and they married last July. The Eatons, who live and train in Eugene, Ore., are still waiting to find time for a honeymoon.

“At our level, you have to make a lot of sacrifices,” Ashton Eaton said. “A lot of that is not spending time with friends or family. So for us, we are so dedicated and, obviously, successful, and that comes with not doing a lot of husband and wife things — yet.”

It comes, too, from pushing each other, sometimes subconsciously. The Eatons’ coach, Harry Marra, recalled a meet in Texas in which the Eatons were set to perform the long jump and high jump simultaneously. Ashton allowed Brianne to go first. She set a personal record.

“I said to the guy next to me, ‘Watch this,’ ” Marra said.

As if on cue, Ashton Eaton followed with his own personal record in the long jump.

“They’re trying to one-up each other — in a good way,” Marra said. “They feed off each other.”

Brianne Thiesen-Eaton, 25, said she and her husband understood what each needed to be successful.

“An athlete’s lifestyle is different than anybody else’s,” Brianne said. “We get that. And it’s a lot easier to stay on track living with somebody who eats the same as me, goes to bed the same time as me, whose goals are the same as mine.”

Ashton, 26, said his focus at shared meets inevitably strayed to where Brianne might be performing. It is hard not to find himself coaching her along the way.

“I was yelling at her and telling her to do certain things on the runway, just to kind of help her,” Ashton said. “She saw me get a personal best in vault and said, ‘Good job.’ It’s cool.”

In other Millrose events on Saturday, the 39-year-old Bernard Lagat set an American record in the 2,000-meter event, winning in 4 minutes 54.74 seconds. Mary Cain, the 17-year-old distance-running sensation from Bronxville, N.Y., won the women’s elite mile event in 4:27.73.

The men’s Wanamaker Mile was one of the most exciting events of the afternoon, as Will Leer, a middle-distance runner from Arizona, zoomed past Lawi Lalang and Nick Willis on the final stretch to win in 3:52.47. Leer entered the final lap clumped near fifth place and said he was growing fatigued.

“You pass somebody, you get more energy,” Leer said. “And down the stretch, only two guys in front of me, I felt good about my chances.”

Alan Webb, the American record-holder for the mile, finished 11th (4:06.11). Webb, who first broke four minutes in the mile in 2001 at the Armory, the first American high school miler to do so indoors, said this would be his final track competition.

“I saw my whole athletic career flashing before my eyes,” Webb said. “I just don’t have that athletic gear anymore. It’s just not there. As much I wanted it to, it’s just not what it was.”

The 31-year-old Webb said he was already making the transition to competing in triathlons. He recognized the symmetry of ending his running career where it essentially began and wanted to leave the Armory with one last memory, and he took a bow.

“It reminded me of going to the gym as a kid, and you’re shooting, and you can’t leave on a miss, you know?” Webb said. “That’s kind of what I wanted. But it is what it is. I’m walking away because I’m just not getting to the finish line like I used to. It’s just the way it is.”
